Bullfrogs are the largest real frog found in North America, weighing up to 0.5 kg and measuring 460 mm in length. Their average length is 100-175 mm. Their color varies from brownish to shades of green, often with spots or blotches of a darker color around their backs. Their back feet are fully webbed.
Bullfrog Tadpole Eggs. Bullfrog tadpoles hatch every month of the year, but they are especially plentiful during the summer months of June and July. Adult female Bullfrogs lay as many as 20,000 eggs at one time so that there are always many tadpoles alive and fighting for survival.hile the tadpoles of competing species may complete metamorphosis in as little as just a few short months, Bullfrog tadpoles can remain in the same state for as long as one to two years before they actually become adult frogs.
